OBERHEIM OB-Xa (x2 Collector vs Player Grade Demo)
video upload by Synth Tailor Electronics
"Here's two very different looking Oberheim OBXA's that just had full restorations at Synth Tailor Electronics. One is in very minty "Collector's Grade" cosmetic condition, and the second one had a very poor life on the road. Surprisingly, the mint OBXa landed in the shop with a lot more problems than the player grade OBXa.
0:00 Intro
0:38 Collector Grade OB-Xa
20:10 Player Grade OB-Xa
Both units had major restorations to each including: Power Supply Rebuild, Voice Cards/Tray Restorations, Left Hand Controller Rebuild, Upper/Lower Motherboard rebuild, and a Full Calibration/tuning. We installed Bourns 25 turn high quality trimmers on the voice cards (x6 per voice card: PW, Initial Frequency, Volts Per Octave.) This is critical to install high quality trimmers in these to have stable tuning!
Surprisingly, me personally liked how the less desirable cosmetic unit sounded, compared to the nicer cosmetic unit. Both were early revision/ both different revision OBXa's, but both sound great. These truly are such an iconic 1980s Analog Synthesizer designed by the great Tom Oberheim.
If you have a broken Oberheim OBXa or any other vintage synthesizer, drum machine, outboard gear, or rare obscure gear that needs repaired/restored, please reach out on our website contact form or email."

video upload by Eternal Engine EMI
"Hello guys! You've been asking for a long time, and I finally got around to recording the tube synthesizer MARS through a line-in. Sorry I couldn't do it earlier; there was a lot of organizational work to handle in these challenging times. This is just a small first attempt."
A few pics and details follow. You can find additional posts featuring the MARS Tube Synthesizer here.



Polyphonic synthesizer based on vacuum tubes.
MARS - the first polyphonic synthesizer based on vacuum tubes. The power and flexibility of oscillators based on the famous R-2R DAC TDA1387, combined with the original fully tube audio path based on the APPARATUS synthesizer circuit, allow you to create a wide range of sounds from punchy aggressive FM leads and acid basslines to soft classic pads and strings. The synthesizer supports full software control and easily integrates into any DAW using the original plugin. All synthesizers are assembled by hand and produced in limited quantities.
Specifications:
Compact RACK format, 5 units high
Fully tube audio path based on the APPARATUS synthesizer
Four oscillators operating in modes: BASIC (Sine, Triangle, Sawtooth, Fixed Pulse Width 1/2, 1/4, 1/8); PULSE; ENSEMBLE and Noise with Hi-Pass and Low-Pass filters
Voltage-controlled tube filter of the second order with self-oscillation with overload
Voltage-controlled amplifier, following the traditional architecture of tube opto compressors

Super Gemini - Preset A1 Jam
video upload by ollilaboratories
"Hello World.. long time no see. A lot of things has been happening, family, work, life etc. I thought that id show some lifesigns, been rearranging in my studio a bit, selling some gear.. getting some new stuff. The biggest thing being the UDO Super Gemini. I have coveted this machine ever since i saw it released and today it is mine.
What you hear is Preset A1 with some slight tinkering.. a tad of reverb in my DAW and thats it. No fuzz, no flashing lights.. just the old BURG in the first moments exploring his new synth.
Note, this is a dynamic jam, so please watch the volume :)
Take care all and talk to you soon!

Meet the minichord Benjamin Poilve
video upload by Seeed Studio
"This project made by Benjamin (https://buttondown.com/BenjaminPoilve) is a pocket-sized instrument that allows anybody to create nice sounding chord progressions. While it is very simple in its usage, it has a lot of musical capabilities. There is an online interface to customise the preset sounds.
The repository for the project is there https://github.com/BenjaminPoilve/min...."
"The minichord has :
21 main chord buttons, divided in 7 column of 3 buttons;
1 "sharp" button (on the top left).
Each column of the main chord buttons is associated to a note of the C Major scale. It is indicated by the letter on the first row of buttons.
Each row of the main chord button is associated to a chord type:
the first row will produce major chords;
the second row will produce minor chords;
the third row will produce 7th chords.
By following the row and the column of each button, we can identify the specific chord associated. Here is the full table of the chord available by the push of a single button
The harp touch zone is divided in 12 different section, stacked vertically. Touching each section will trigger a note. Notes can be held by keeping the contact with the section.
This touch zone can be "strummed" by sweeping the finger across all sections, or individual notes can be triggered.
The preset selection buttons can be used to switch between preset. The minichord has 12 internal preset (see "Default presets"), that can be replaced by custom presets (see "Making custom presets"). Going up after the 12th preset will circle back to the first, same as going down before the first will circle back to the 12th.
The main led will shine with a different color for each preset to help you identify the current selected one.
Each of the three potentiometer has one main function, designated by the marking on the enclosure :
The first potentiometer from the top sets up the volume of the chord section;
The second potentiometer from the top sets up the volume of the harp section;
The third potentiometer from the top is assigned to a different function for each preset, depending on what is usefull for it.
The rythm mode button (on the top right) has two basic mode:
discrete: the chord only stays on for as long as you keep the relevant button pushed. In that mode, the indicator led will be off.
continuous: the chord will keep playing until you push a new button, and seamlessly switch to the next chord. In that mode, the indicator led will be on.
Simply push the rythm mode button to switch from one mode to the other. That button may also be used to switch to the arpegiator mode with a long push, but that subject is handled in the "Advanced usage" section.
Charging is done through the mini USB jack available on the buttom right of the minichord. Connection to any USB outlet will do, and it will draw 500ma of current.
When charging, the top right led will shine red.
Full charge should be below 3 hours, and the top right led will shine green once the full charge is attained. Once fully charged, the minichord will play for around 7 hours.
When the battery is getting low, the main led will pulse. Once the pulsing start, the minichord can play for around 15 minutes more. You can play the minichord while plugged in."

Bill Wolfer jams on the Cherry Audio P-10 #cherryaudio #synthesizer #vst #musicproduction
video upload by Bill Wolfer
"I used a Sequential Circuits Prophet 10 in 1980 on Stevie Wonder's Hotter Than July album. That was a long time ago, but to my ears, this emulation is spot on. Plus, it's got things the original didn't—it's a very deep bit of gear. Every sound in this video is direct from the P-10, effects and all. I didn't use any external reverb, EQ or delays.

ANA 2 Patch Example: Macro Controller
video upload by Mystic Circuits
"This is by far the easiest patch that you can make with your ANA 2 but it is deceptively powerful. With no inputs you can still use the knobs on ANA to send a static voltage into the analog logic circuits. This creates 9 correlated output voltages that are perfect for controlling other modules with lots of CV inputs. Here we have one ANA controlling our landscape NOON and a second ANA controlling a Mutable Instruments Beads ~ 3DVCA combo. Check out our website for more info or to order - we will have a handful of black panel units available on Black Friday!"

3 oscillator semi-modular synth, complex modulation capabilities, MIDI & CV control.
Probably no other monophonic analog synth has this amount of sound bending capabilities at your fingertips on an ultra-compact footprint. Directly prepatched and switchable are:
VCO2 synchable to VCO1
VCO3 can modulate either VCO2 (only) or VCO1 + 2
VCO3 can modulate the filter
VCO3 can be taken out of the audio path completely, becoming an 'invisible' source for modulation only
the filter envelope (VCF) can modulare VCO2 ('sweep VCO')
VCF has two modes of keytracking
both LFOs can control VCOs AND filter cutoff at the same time and with independent settings
LFO1 can do S&H by sampling LFO2 (making them interdependent) or the noise generator
oh, there actually is an "OSC4" which is white noise (with its own level control), in addition to the white noise setting on VCO3 and the white noise setting on LFO2. That's 3 noise generators in just one synth.
glide function
VCA switchable positive / negative
envelope trigger switch
...
In addition, there are the patch points which add PWM modulation, external audio insert points, individual VCO outs, V-gate in on LFO1 +++
